Any particle that obeys Bose-Einstein statistics but not the Pauli exclusion principle; all nuclei with an even mass number are bosons.
A particle that has integer intrinsic angular momentum (spin) measured in units of h-bar (spin =0, 1, 2, .). All particles are eitherfermions or bosons. The particles associated with all the fundamental interactions (forces) are bosons. Composite particles with even numbers of fermion constituents (quarks) are also bosons.
Subatomic particle whose spin can only take values that are whole numbers or zero.
In physics, an elementary particle whose spin can only take values that are whole numbers or zero. Bosons may be classified as gauge bosons (carriers of the four fundamental forces) or mesons. All elementary particles are either bosons or fermions.
Unlike fermions, more than one boson in a system (such as an atom) can possess the same energy state. When developed mathematically, this statement is known as the Bose–Einstein law, after its discoverers Indian physicist Satyendra Bose and Albert Einstein.
